PAGEEDITORS: Ariela Zebede, David Jelke, Brad Jackson, Jacob Stern Natland Note:(8/18/13) This is where I will post comments about suggested and necessary improvements to your page as you complete it while we are going over the content for your topic. Keep an eye on this note, as I will post new ones from time to time. NOTES:
Bottom half of glass acts as a convex lens, top half as a concave. Image is inverted on the bottom and real in both.
convex outside of focal pt.
White light is separated into lights of different frequencies by a prism using the process of refraction.
Magnifying glasses use convex lenses which enlarge images within the focal point.
Fibre optic cables redirect light shined inside them towards the other end of the cable using reflection.
Rainbows created when droplets of water remaining in the air act as a prism and refract white light into light of other colors.
Because the speed of light differs in a vacuum and our atmosphere, light is refracted when it enters Earth.
Mirages are caused by hot temperatures affecting the speed of light. (see video)
